This invention relates to gas generators or carburetor installations.

This invention has utility when .incorpo rated in entraining oratomizing means for 51 liquid fuel especially as adapted for domesticlighting, cooking and heating purposes.

Referring to the drawings Fig'.V 1 is a side elevation, with partsbroken away, of an embodiment of the invention as a low pressure fuelgas installation;

Fig. 6 is a vertical section through the receiver of Fig. 1;

Fig. 7 is a section on the line VII-VIL Fig. 6, looking in the directionof the arrow; and

Fig. 8 is a fragmentary view in plan of the fan or air pump.

Electric motor 1 is shown as having shaft 2 effective through belt 3 fordriving pulley 4 on shaft 5 fixed with bladed drum 6 as an air deliverydevice or fan designed to have a wide range of capacity for deliveringagainst a constant back pressure to bev developed and maintained by saidfan.V From this fan 6 extends pipe 7 upward and then down into vessel 8.

This pipe 7 has upturned multiple `iet termini 9 disposed below andVithin'chamber 10 fixedly mounted in this vessel 8 by brackets 11, 12,13. Clamps 14 position the pipe 7 with this chamber 10. Liquid. as water15, may be in the vessel 8 with free communication through open end 16as well as port 17 to the interior of the chamber 10. The region of thiswater 15 within the chamber 10 provides a wat-or piston 18 which, in thenormal pump operation, is effective to be depressed to bring the levelof the water 15 about the chamber 10 to a desired head for maintainedpressure above the port V17. When excessive air pressure is developedwithin chamber 10 the liquid piston within` said chamber is depressed touncover port 17 and when this happens the excess air passes through saidport and upwardly through the liquid confined between the chambers S and10. As the port 17 is positioned above the jet termini 9 it will beevident that the relief or escape of excess air pressure is edectedwithout depressing the liquid piston sutliciently to uncover the jettermini 9 and hence humidification of the air delivered by the latter atall times is assured. In practice, the

Vmot-or 6 is so designed that this point of maximum pressure for thewater head approximates the bac-k pressure for which the fan 6 isdesigned. There is ready adjustment below this pressureby the reductionof the head of the water 15 by reducing its quantity. There isaccordingly herein an automatic relief valve as asafety device Workingeffectively as a humidifier.

This device is a simple relief, insuring safety against excess pressure,while automatically maintaining a reserve as a balance for taking careof widely diiferent rates of fuel consumption without fluctuation ofpressure as additional apparatus may be used. From this chamber 10extends `pipe 2O past check valves 21, 22, in duplicate, as one tosupplement the other against pressure iiow back` into the chamber 10from gas generator container 23. This pipe 2O enters this closedcontainer 23 and extends to the lower portion to have jet termini 2e ofdischarge capacity area approximating that. of the pipe 2O for avoidanceof back pressure. The jet termini 9 int-o the chamber 10 are likewise ofan' area to take care of the capacity of the pipe 7 at the pressure tobe developed normally by the fan (i. These jet termini 2li for y thesupply of -air to the gas generator container 23 are submerged belowliquid fuel 25, as gasoline, or other volatile liquid of a. suitablecharacter. This container 23 may be charged by the removal of air tightclosure cap 26. Cleaning out of this container 23 may occur by theremoval of the plug 27 adjacent the bottom. Plug 28 may be rew moved forwashing out the humidifier 8, 10.

From the upper portion of this container 23 of the generator extendspipe 29 past check 1 y this pipe 29 to reservoir 32. As there may becondensation in this reservoir 32 such may be drawn off by the removalof plug 33 near the bottom. thereof. In practice, even for plantsinvolving a quite wide range of gas consumption, it may not be necessaryor even desirable to include the receiver or reservoiry 32, for thehumidifier chamber 10 is a pres-- sure equalizing reserve even asagainst intermittent operation of the fan 6. However, for asupplement-al reserve, this reservoir 32 is effective and has therefromgas line to gas consuming equipment as may be desired, as to a hot plateburner 35 having gas flow thereto determined by valve 36. Shutting offthis valve 36 checks flew back into the reservoir 32. rEhis does notbring about back iiow from this reservoir 32 into the container 23iecause the check valves 30, 31, preclude back `flow. However, there isbuilt up, in air chamber 3'? over fuel 25 in the gas generator container23, such a degree of back pressure that further flow or supply airthereto by the line 2O is checked. This does not mean a back flow intothe humidifier, for the check valves 21, 22, in the line 20, preventsuch reverse flow.

lf the fan 6 be operating, the delivered air depresses the liquid piston13 to expose the port 17 and as the fan 6 may continue to operate, suchexcess of pressure air merely bnbbles off out of the vessel 3 and hasentrained therewith no combustible mixture or other conditions whichtend to develop any lire hazard. At once the valve 36 is opened,pressure flow from the reservoir 32 may be replenished by the generator23 andrhumidilier chamber 10 automatically and instantaneously to cutoff pressure fluctuation.

TWith the installation of the reservoir 32 and a capacity for thehumidilier chamber 10, the motor l may be automatically controlled byintermittent operation instead of being run continuously or selectivelyas the gas equipment is used. To this end the gas delivery line 34 hasbranch 33 te pressure responsive bellows 39 elfective as to upperdiaphragm Ll0 for rocking lever 4:1 on its pivot bearing 4:2 in tiltingvessel Li3 having terminals 44, 45, therein to be submerged by mercury46 as the pressure in the line 33 falls. This means that electriccurrent supply line el?, as extending to terminal 44, isV thus connectedto electric line 4-8 extending to the motor 1 in parallel with electriccurrent supply line 49. There is thus automatically a starting of themotor 1 for operation of the fan 6. As the pressure in the branch line38 is built up, the bellows 39 operate the lever l1 to again tilt thevessel i3 so that the mercury i6 therein is clear of the terminals 4.4,45, and this automatic switch is thus opened.

What is claimed and it is desired to secure by Letters Patent is:

1. Apparatus of the character described comprising a humidifier, a gasgenerator and a gas storage tank connected together in series, with thehumidifier delivering to the gas generator and the latterdelivering tothe storage tank, a blower functioning to force air through Vthehumidifier to the gas generating tank and to provide the pres surenecessaryfor forcing the generated gas from the generating tank to thestorage tank and from the latter to the point of consumption, a motorfunctioning to drive the blower, a pressure responsive device connectedto the gas storage tank and a switch operable by the pressure responsivedevice to open the motor circuit when the pressure in the storage tankexceeds a predetermined value and to close the motor circuit when thepressure .in the storage tank falls below said predetermined value.
